Two early Cretaceous fossils document transitional stages in Alvarezsaurian dinosaur evolution

Abstract:

Highly specialized animals are often difficult to place phylogenetically. The Late Cretaceous members of Alvarezsauria represent such an example, having been posited as members of various theropod lineages, including birds [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]. A 70-million-year ghost lineage exists between them and the Late Jurassic putative alvarezsaurian Haplocheirus [12], which preserves so few derived features that its membership in Alvarezsauria has recently been questioned [13]. If Haplo...
